Overmassive black holes and little red dots naturally form in simulations
Our cosmological initial conditions are based on the simulation Phi-4096 of ref. 51. In this work, a dark-matter-only N-body simulation was performed in a comoving box of side length 16 h−1 Mpc. The initial condition is generated by MUSIC52 at a redshift of 127. The cosmological parameters used follow the latest measurement by Planck53: Ωm = 0.31, ΩΛ = 0.69, Ωb = 0.048, h = 0.68,
